PATENT @ENCEo HUNTER, OF BERKELEY SPRINGS,

IEST VIRGINIA CHURN.

SPECLFICATION forming part of Letters Patent No. 787,180, dated April l1, 1905.

Application filed December l, 1904. Serial No. 235,094.

Re it known that we, Hnxui' I-I. IIUNrnnand l Srnwwn'r Il. lItxTni-t, citizens of the United States, residing at Berkeley Springs, in the county ot' Morgan and State otl 'est \f'irginia, have invented new and useful Improvements in Churns. of which the following' is a speci` lication.

This invention relates to certain new and useful improvements in churns, and has Vfor its general object to provide a churn which g shall be simple in construction and easy in y operation and one which maybe economically manufncturtal.

Further objects of the invention relate to details of construction and to combinations and operationsy ot' parts, as will more clearly appear from the description to follow, and particularly in the claims appended hereto.

In order that the invention may be clearly understood` we have illustrated the same in the accompanying drawings, in whichw Figure l is a sectional elevation. Fig. 2 is a sectional plan view taken on the line 2 Q of Fig. I. Eig. 3 is a rear elevation otl a part otl the frame, and Fig. is a plan view of the closure.

Referring now to the drawings, I indicates a base, upon which are supported uprights 2 and a recessed chock-block B, the latter being for the purpose of positioning the churning vessel I on the base I. Toward their upper ends the uprights '2 are connected b v a crossbar .3, on which is journaled atone side adrivegear t3. provided with a crank-handle T. At some distance below the cross-bar 5 we provide a longitudinal bearil'ig for receiving and ,i centering the shaft 2) of thedasher. The shaft l may be inserted in the l. earing S through the l medium of a hinged member IO thereof, and l a lock-plate il, pivoted on one ot' the uprights L). is provided for holding the hinged member closed when the shaft has been iixed in posil tion in its bearing. clip IQ on the locki plate engages over the hinged member to prevent the lock-plate from falling out of eni gagement therewith. l

The shaft .V) is formed in two separable parts. The lower part of the shaft or that part carl rying` the dasher is provided iu its upper end with a slot 1?), and the upper part It is in the forni of a sleeve litting over the end of the lower portion of the shaft and is provided with a bar I5. extending across the Same, which is designed to engage in the slot I3 to prevent relative movement between the two parts of the shaft. On the upper end of the part Ii is mounted a gear-wheel 16, which is adapted to mesh with the drive-gear (3. The dasher is formed by a series of horizontally- `disposed blades mounted in and extended through apertures formed tln'oughout the length of tbe lower portion of the shaft 9 and so disposed as to impart a spiral formation to the blades IT. One outer end of each of these blades is lixedly secured to a strip IS, which in operation is designed to work in close proximity to the wall of the vessel et. The portions of the blades IT on the opposite side of the shaft to that at which their opposite ends are respectively connected to the strip IS are provided with knife-edges on their Vforward or working sides, as indicated at I9. The closure for the vessel I, which is indicated generally by the numeral '20, comprises a cap 21, which is adapted to be removably litted over the upper end of the vessel 4C and provided on its upper side with two or more elongated apertures. hotatably mounted on the cap is a disk "22, which is provided with apertures 23, adapted to be brought into and out of aliucnient with they corresponding apertures in the cap 2l. The disk is held in position through the medium of a collar 25, having a hub secured to the cap 2l. which hub provides a bearing for tue disk 22, as will be understood.

The manner in which the parts are assembled in position for use is clearly shown by Figx l, and in Fig. l we show a lever Q5, pivoted on one of the uprights L) at one end and frictionally engaging' one of two metal braces 2o, provided for each of the uprights 2 at its outer end, said lever being adapted to be brought down into engagement with the col- I lar '25 to lirmly hold the churning vessel in position and the lever being adapted to spring' under a shoulder 2T, formed on the brace 2G for holding the parts in their clamped position. For the better securing of the vessel in the manner just described the collar 25 is provided on its upper face on one side with a groove 28, and the lever' 25 may be provided with a piece of rubber tubing` 29 for engaging in thc groove 28, although both thesaid groove and said rubber tubing may be dispensed with. Said groove is desirable, however, as tending to prevent rotation of the churn as the butter begins to form. To remove the churning vessel with its shaft from the frame of the machine, the lock-plate 11is lifted and the hinged member 10 opened, When the vessel with its shaft may be removed from the frame. To remove the dasher from the vessel, the upper portion or sleeve 14 of the shaft is pulled off. The closure 2() is then removed and the dasher lifted out of the vessel.

The churning vessel 4 is preferably made of some kind of crocleryware, and in order to permit the operator to see when the cream has been suciently churned the disk 22 may be turned to bring its apertures and those in the cap 21 into alinement, when either by looking through the apertures or by inserting a suitable implement the desired examination of the contents of the vessel may be made. All of the parts of the dasher within the vessel 4C are of wood, as we find that metal has a tendency to make the butter blue. The spiral strip 18 of the dasher of course operates to constantly free the inner side of the vessel from adhering particles of butter, while the blades 17 in l conjunction with said strip also afford the necessary churning operation.

The knife-edges 19 permit the portions of the blade so conl structed to readily cut through the butter l while balancing the action of the shaft suflil ciently to permit easy movement and beating l or churning the cream and diminish the resistance to the turning of the shaft.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a churn, in combination with a churning vessel, -a cap adapted to fit over the same and provided with apertures, a disk rotatably mounted on said cap and provided with apertures adapted to be brought into and out of alinement with the apertures in the cap, acollar secured to said cap and located above said disk, a lever adapted to engage said collar, a dasher in said vessel, and means for rotating said dasher.

2. In a churn, in combination with a churning vessel, a shaft extending into the same, means for rotating said shaft, and a dasher mounted on said shaft comprising a series of spirally-arranged transverse blades each of which is mounted at one end in a strip and having their opposite end portions provided with knife-edges on one side.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
